I have a problem in my sequencing results. I cloned a GUSNOS insert into
a plasmid and afterwards a promoter in front. When I received my
sequencing results the forward sequence of my promoter was fine but the
reverse ( the annealing was at the beginning of the GUS gene) was
superimposed after 130 base pares. This happened exactly at the level of
the cloning site before the GUS fusion.....
I suspect that my culture contains a mixture of two plasmids, the
transformed and the not transformed....or in the worst case two
different repetitive sequence of the GUSNOS.
How could I figure this out?
Is it possible to separate eventually the two plasmid?
Thank you very much
